Question 1052598
x, how many hats
y, how many T-shirts


PRICES for the items are $2 per hat, and $5 per T-shirt.


Write equations that account for total items, and the cost.
{{{system(x+y=100,2x+5y=380)}}}



Intersection point is the solution.
Cartesian coordinate points are as (x,y).
{{{graph(400,400,-5,100,-5,100,-x+100,-(2/5)x+76)}}}

Not easy to read the graph displayed here.  You can find an accurate answer ON PAPER GRAPH, because controlling the scaling is easier.
